Re: [MBZ] AC compressor engage signal on a euro 123 wagon
Mit Klima, or Sans Klima? If it has Klima, that is where you start. Klima relay fails often. Otherwise, I'd start at the plug closest to the clutch. Likely if you have voltage there when the clutch should be engaged, the clutch coil is bad. If no volts there, every case I have encountered has been a Klima relay gone over the hill.

WDB 123 193 120 14388 It is the older style unit with the vertical buttons in the middle. I guess I need to do some reading on how these control units typically fail and how to test/troubleshoot them. This motor is from a 2006 320 cdi, so it is a bit of a hybrid.
